SPECIFICATION forming part of Letters Patent N 0. 671,081, dated April 2, 1901.

Application filed July 30, 1900.

To all [Uh/H117 (it Hut-1f concern;

Be it known that. l, ELMER Einiswon'rn GREEN, a citizen of the United States, residing at Santa Clara, in the county of Santa Clara and State of California, haveinvented certain new and useful Improvements in Apparatus for Making Gelatin Dynamite; and I do doclare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to Lhe accompanying drawings, and tothe letters of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in apparatus for the manufacture of gelatin dynamite, whereby doublethe quantity of the product may he produced in a given time than with machines commonly in use and with a greater degree of safety.

In carrying out my invention I provide means whereby the guncotton and nitroglycerin are thoroughly mixed together at a suit-- tended with much danger.

able degree of temperature in a receptacle which is mounted on a rotary platform, thus allowing the receptacle to be positioned un' derneath a stirrer for incorporating dry absorbents with the gelatin without necessitating the removing, of the gelatin from one receptacle to another, which is frequently at- In the manufacture of gelatin dynamite it is first necessary to make the nitrogelatiu by a different mixing motion than is required in the mixing of the gelatin dynamite.

This I am able to accom plish by means of differently-consti-ucted stirrer-s and without the necessity of removing the material from one receptacle to another.

My invention will be hereinafter more fully described, and then specifically defined in the' appended claims.

I illustrate my invention in the accompan-ying drawing, which, with the letters of reference marked thereon, forms a part of this application, and in which drawing I have shown a front elevation of the apparatus, parts being shown in section.

Reference now being had to the details of the drawing by letter, A designates a rotary platform having a flanged edge A and a circular band or track B adjacent to the outer Serial No. 25,296. \No modeL;

I marginal edge of the bottom of the platform. Directly underneath said track is a series of rollers C, mounted in suitable hearing mem bers O, which may be supported on concrete orother'suitable foundations. On these rollers the platform is designed to rest' and rotate. Near the center of the platform and underneath the same is a circular grooved flange of the guide E rests. Upon the platform are mounted the two tanks andG, which are designed to contain hot water, the water being supplied through the feed-pipe II, which has communication with the tanks through the valve-regulated pipes H, leading into the stuffing-box I, in which the lower end of the pipe H is allowed to turn steamtight. Each tank contains a bronze kettle R, having a flanged top resting on the upper edge of the tank, a suitable space intervening between the outercircumference of each kettle and the inner wall of the tank, so as to allow the heated water to entirely surround the kettle. The outlet-pipe J, which passes up through the platform, communicates with the pipes L, which are valve-regulated, through the stuffing-box I, which turns steam-tight about the upper end of the pipe J. I

M M designate upright posts which are flanged and support in suitable bearings the shafts N and N.' The shafts N have bevelgearwheels at on their inner ends, while pulleys O areseeured to rotate with said shafts at their outer ends. cross-beams Q, and Q is the hollow shaft R, having a bevel-gear R, which meshes with the bevel-gear n, and a'seeond gear K is keyed to rotate with a shaft S, which turns within the hollow shaft R. Said bevel R meshes with a pinion N on the shaft N. The shafts R and S have splines, so as to allow the shafts to be raised and lowered through the gearwheels. At the lower end of the shaft R is keyed the stirrer P, while a concentric 'stirrer P is keyed to and rotates with the shaft S. P is a vertically-movable brace, whichis apertured, through which the shafts pass, and which. rises and lowers with the latter.

These stirrers are adjustabiy raised and lowered in a similar manner as those before described on the opposite side of the apit will be noted that the shafts S and R, which rotate the stirrers in opposite directions, pass through collars X, which collars are secured to the timber P of the frame, and the said shafts are thus verticall mov able with the said timber P In order to provide for the vertical movement of the frame carrying the stirrers, the horizontal brace-timber P is provided at its ends with grooves which are fitted over guideways M which are provided upon the inner faces of the uprights M, and the entire frame carrying the stirrers and their connections may be raised and-lowered when it is proposed to raise the stirrers from'the kettles or toreturn them thereto, as will be readily understood.

In operation the water in the tanks is brought to a temperature of approximately 140 Fahrenheit. The nitroglycerin and guncotton are placed in the kettle (Eh-and the agitators or stirrers P and P are lowered into the kettle and are rotated for, say, twenty minutes,- when the mixture becomes nitrogelatin. This done, the stirrers are raised, and the platform is rotated with the tanks and kettles thereon, so that the kettle containing thenitrogelatin comes directly underneath the stirrers W and W. The stirrers W and W are then lowered ihto the kettle,

5. In combination with the rotatable platform, the circular track secured to its under face, the antifriction-wheels on whichsaid track rests, the tanks, kettles mounted therein, the feed and outlet pipes communicating with the tanks, the grooved plate underneath said platform, the circular guide-plate having a flange guided in said groove, the stirrers and means for operating same, as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
